[Plugin: Image Gallery] Image not displaying

This is a great idea – simple is key. However, I cannot get the JPG to display. Even with full-path URL to the file (which displays fine in a plain browser window). I set to size 238×175, default fades and transition times (1000, 1200, 4000) and provide only a URL to the image – no link URL. If I put header and footer text in, that displays, but no image. Would love to use this but doesn’t look like it’s going to work. ??

Also, instead of specifying each and every image, it would be great to have an option to just display all the contents of a directory, especially since I explicitly DO NOT want to have links on each image.
